On top of having a higher cash flow without having a loan on a property, there is not much risk in owning real estate without a loan. Yes, the property value can decrease in the short term, but people will always need a place to live. The real estate market has been the most consistent market to ever exist. Over time, properties have always gone up in value at the same or even greater pace than inflation.
Along with real estate being a stable investment, the CHES token itself is built with long-term sustainability in mind. The token is a deflationary token, meaning over time, the total token supply will be decreased to help push the price of the token up. Please keep in mind that the only tokens that will be burned are the tokens that are spent on NFTs. Tokens that are held in wallets will never be burned.
